- The glacial acetic acid in the diluted form used in vegetables and food preservation,flavoring in the slice, sausage, canned fruits and also it used to treat the bacteria and fungal infections.
Answer:
Answer D. Picture II shows a chemical change, because the same substance changes form
Explanation:
This is the temperature that water molecules slow down enough to stick to each other and form a solid crystal
This is a decomposition reaction, where ammonium nitrate is heated and decomposed to gaseous water and dinitrogen oxide.
Formulas for reactants and products with states are as follows;
ammonium nitrate - NH₄NO₃ (s)
water - H₂O (g)
dinitrogen oxide - N₂O (g)
balanced reactions when the masses of both sides of the equation must be balanced
Balanced chemical equation
NH₄NO₃(s) ---> 2H₂O(g) + N₂O(g)
